Secondary Zinc-Air Cell Investigations

Abstract

Zinc-air cells have been developed that are capable of delivering over 50 cycles. These cells were constructed with silver-amalgam air-cathodes, nickel screen charging electrodes, and teflonated zinc anodes. The major failure modes encountered in this study were: shorting by zinc penetration, loss of capacity by the zinc anode due to edge-corrosion and surface densification, platinum poisoning of the zinc anode when employing platinum-catalyzed air- cathodes, and passivation of the zinc anode by electrolyte starvation. The means of overcoming these problems are presented.
